Nice! 48 00:03:07,000 --> 00:03:14,000 It looks like the build team are off to a flying start, but when they calculate the speed of the belt sander using a tachometer... 49 00:03:15,000 --> 00:03:17,000 It's saying 550 RPM. 50 00:03:19,000 --> 00:03:21,000 That's going 43 miles an hour. 51 00:03:22,000 --> 00:03:23,000 That's it? 52 00:03:23,000 --> 00:03:24,000 Not fast enough. 53 00:03:24,000 --> 00:03:31,000 Why don't we rig up something else? We could do something with a grinder. That's 30,000 RPM. 54 00:03:31,000 --> 00:03:34,000 Why don't we just jack up a car? 55 00:03:34,000 --> 00:03:41,000 Jack up a car, attach the wheels to the actual car wheel, and then just floor it. 56 00:03:42,000 --> 00:03:44,000 Brilliant and potentially deadly. 57 00:03:44,000 --> 00:03:47,000 So, a perfect mythbusters rig. 58 00:03:47,000 --> 00:03:53,000 The car is jammed up against the wall in case it falls off the jack while the wheels are at high speed. 59 00:03:53,000 --> 00:03:59,000 Yeah, and with the angle that we've got the fork set, it's not gonna slip forward, it's gonna slip back, if anything. 60 00:03:59,000 --> 00:04:03,000 They tape up the treads to create a smooth test track. 61 00:04:03,000 --> 00:04:06,000 Then position Scotty's rig with a C-stand. 62 00:04:06,000 --> 00:04:07,000 Do you see the way it's sitting? 63 00:04:07,000 --> 00:04:08,000 Yeah, it seems fine to me. 64 00:04:08,000 --> 00:04:09,000 It seems fine to me. 65 00:04:09,000 --> 00:04:11,000 It's alright, not too much pressure on the wheel. 66 00:04:14,000 --> 00:04:15,000 There we go. 67 00:04:15,000 --> 00:04:16,000 15. 68 00:04:18,000 --> 00:04:19,000 25. 69 00:04:19,000 --> 00:04:24,000 If the toy wheels stay on the wagon, there could be mileage in this myth. 70 00:04:24,000 --> 00:04:25,000 30. 71 00:04:25,000 --> 00:04:28,000 There went one wheel. What was that mile per hour? 72 00:04:28,000 --> 00:04:29,000 35. 73 00:04:29,000 --> 00:04:31,000 Well, they're not rated for much, are they? 74 00:04:31,000 --> 00:04:37,000 35 miles per hour might be disappointing, but Jamie's not convinced about the rig. 75 00:04:37,000 --> 00:04:42,000 I think it's about the weight, and I don't like this setup because we've got this C-stand on here. 76 00:04:42,000 --> 00:04:43,000 Okay. 77 00:04:43,000 --> 00:04:49,000 I'd like to try one and just hold on to it because I can make it a feather weight, which is all it should be. 78 00:04:49,000 --> 00:04:50,000 Okay. 79 00:04:50,000 --> 00:04:55,000 Rather than risk Jamie's hands on approach, they decide to modify the rig. 80 00:04:55,000 --> 00:05:00,000 What we've been having as a problem, our first rig, is putting too much pressure on the wheels. 81 00:05:00,000 --> 00:05:02,000 So what we did is we changed it up a little bit. 82 00:05:02,000 --> 00:05:07,000 We're just having a car held in place. No pressure on top, but it's just resting on the tire. 83 00:05:07,000 --> 00:05:12,000 And this way it'll give us a more accurate result of what a car would actually be doing. 84 00:05:12,000 --> 00:05:14,000 Okay, Scotty, start her up. 85 00:05:16,000 --> 00:05:21,000 With a wooden shoe holding the toy car in place, Scotty steps on the gas. 86 00:05:21,000 --> 00:05:23,000 45. 87 00:05:23,000 --> 00:05:25,000 50. 88 00:05:25,000 --> 00:05:26,000 Wow, look at that. 89 00:05:26,000 --> 00:05:28,000 65. 90 00:05:28,000 --> 00:05:30,000 70. 91 00:05:31,000 --> 00:05:32,000 85. 92 00:05:32,000 --> 00:05:34,000 It's out of its shoe. 93 00:05:34,000 --> 00:05:36,000 That's pretty cool. 94 00:05:36,000 --> 00:05:37,000 It held in there. 95 00:05:37,000 --> 00:05:38,000 Yeah. 96 00:05:38,000 --> 00:05:40,000 I can't see anywhere on them. 97 00:05:40,000 --> 00:05:42,000 They look fine. 98 00:05:42,000 --> 00:05:44,000 But over about a quarter mile, you think they'd hold up?

118 00:06:55,000 --> 00:06:56,000 Ready to plug in. 119 00:06:59,000 --> 00:07:00,000 Duster! 120 00:07:03,000 --> 00:07:04,000 Next to my set! 121 00:07:08,000 --> 00:07:09,000 This is really fennec-y. 122 00:07:09,000 --> 00:07:11,000 It looks easy on paper. 123 00:07:11,000 --> 00:07:12,000 That's it! 124 00:07:13,000 --> 00:07:14,000 Right there! 125 00:07:14,000 --> 00:07:15,000 73! 126 00:07:16,000 --> 00:07:17,000 76.2! 127 00:07:18,000 --> 00:07:19,000 70! 128 00:07:19,000 --> 00:07:22,000 We're balancing at 74.9! 129 00:07:22,000 --> 00:07:26,000 The wind tunnel experiment backs up the wheel test results, 130 00:07:26,000 --> 00:07:31,000 suggesting toy cars can achieve speeds of over 70 miles per hour. 131 00:07:31,000 --> 00:07:36,000 The myth that a toy car can lick a real car is shaping up nicely, 132 00:07:36,000 --> 00:07:38,000 in the lab at least. 133 00:07:40,000 --> 00:07:42,000 The mythbusters lab tests are complete, 134 00:07:42,000 --> 00:07:45,000 so it's time to shift things up a gear. 135 00:07:46,000 --> 00:07:49,000 Carrie, I think those lab results you guys came up with on the car is really impressive. 136 00:07:49,000 --> 00:07:54,000 I mean, it really seems at this point that a toy car might be a contender against a real car. 137 00:07:54,000 --> 00:07:56,000 We don't know how it's going to do on the actual day, 138 00:07:56,000 --> 00:08:00,000 but under perfect lab conditions, we've got up to 70 miles an hour on our wind tunnel. 139 00:08:00,000 --> 00:08:04,000 Well, they do seem like they go pretty fast, but I think we can do better. 140 00:08:04,000 --> 00:08:08,000 I think we should each build our own car that we think could be the fastest. 141 00:08:08,000 --> 00:08:13,000 We can use any material, each of us gets a shot at making the fastest car. 142 00:08:13,000 --> 00:08:17,000 Scotty and Carrie kick things off by customizing production models, 143 00:08:17,000 --> 00:08:21,000 and come up with Hot Pink and Gecko. 144 00:08:21,000 --> 00:08:23,000 Mine's the prettiest. 145 00:08:23,000 --> 00:08:29,000 Jamie's up next, and as his business includes building toy prototypes, he's on Familiar Grand. 146 00:08:29,000 --> 00:08:32,000 It actually hasn't been that long since I've played with toy cars. 147 00:08:32,000 --> 00:08:36,000 In fact, with what I do for a living, I do it all the time. 148 00:08:36,000 --> 00:08:41,000 So this is what Jamie calls work when he's not on Mythbusters. 149 00:08:41,000 --> 00:08:45,000 Aha! The van kicks butt, and I have no idea why. 150 00:08:45,000 --> 00:08:48,000 But in no time, his trained eye spots something. 151 00:08:48,000 --> 00:08:54,000 One thing that I've noticed about these two cars is that they have significantly different wheelbase widths. 152 00:08:54,000 --> 00:08:59,000 The van is wider and can't like bounce around from sidewall to sidewall. 153 00:08:59,000 --> 00:09:03,000 I think that that may be the key difference between all these little cars. 154 00:09:03,000 --> 00:09:06,000 Jamie decides to build a car from scratch. 155 00:09:06,000 --> 00:09:09,000 Well, it's a little tiny pizza cutter wheel. 156 00:09:09,000 --> 00:09:16,000 So Adam rises to the challenge, and if there's ever a quick conclusion to be reached, he's your man. 157 00:09:16,000 --> 00:09:23,000 That's all I need to see. The van seems to go as fast as Scotty's supercar here. 158 00:09:23,000 --> 00:09:26,000 I've got an idea already in my head. 159 00:09:26,000 --> 00:09:30,000 I think I'm just going to go for my idea, see what I get. 160 00:09:30,000 --> 00:09:31,000 Hey, Gowan. 161 00:09:31,000 --> 00:09:32,000 Don't do that.

357 00:21:25,000 --> 00:21:29,000 Before long, there's a feeding frenzy around the Mythbusters stall. 358 00:21:29,000 --> 00:21:30,000 Sure, I'll do it. 359 00:21:30,000 --> 00:21:31,000 Okay. 360 00:21:31,000 --> 00:21:32,000 Sure, why not?

That's the last one. We're done. 388 00:23:43,000 --> 00:23:46,000 For Kari, it's not a moment too soon. 389 00:23:46,000 --> 00:23:51,000 I was yawning all day, the point where my cheeks were hurting and my eyes were watering. 390 00:23:53,000 --> 00:23:59,000 All right, well, after testing 50 people in the field, our largest sample we've ever used on Mythbusters, 391 00:23:59,000 --> 00:24:04,000 the results are in, and when the people we tested got no seed yawn, no stimulus, 392 00:24:04,000 --> 00:24:10,000 they yawned 25% of the time. When they got stimulus, they yawned 29% of the time. 393 00:24:10,000 --> 00:24:14,000 Well, it's not dramatic, but it seems like it's pretty good to me. 394 00:24:14,000 --> 00:24:16,000 What do you guys think? Busted, plausible, or confirmed? 395 00:24:16,000 --> 00:24:19,000 Given how large our sample was, I'd say it's confirmed. 396 00:24:20,000 --> 00:24:23,000 There's little doubt. It does seem to be contagious. 397 00:24:23,000 --> 00:24:27,000 And I bet the audience at home right now is probably yawning. 398 00:24:29,000 --> 00:24:31,000 And that's what we're gonna do. 399 00:24:43,000 --> 00:24:48,000 You know, Jamie, this coming up is a question that has plagued the breakfast table for generations. 400 00:24:48,000 --> 00:24:54,000 And that would be whether buttered toast falls, buttered side up, or down more often. 401 00:24:54,000 --> 00:24:56,000 Exactly. 402 00:25:00,000 --> 00:25:02,000 You know, Jamie, it is a truth. 403 00:25:02,000 --> 00:25:08,000 Universally acknowledged that a man in possession of a good fortune must be in want of a myth to bust. 404 00:25:08,000 --> 00:25:12,000 Well, it has been an absolutely capital year for busting myths. 405 00:25:12,000 --> 00:25:14,000 Indeed. Most agreeable. 406 00:25:14,000 --> 00:25:15,000 More tea, sir. 407 00:25:15,000 --> 00:25:16,000 Thank you. I'll get it. 408 00:25:22,000 --> 00:25:24,000 Buttered side down again? 409 00:25:24,000 --> 00:25:27,000 Well, that sounds like something we need to test, and I have an idea. 410 00:25:27,000 --> 00:25:29,000 Well, I have an idea too, actually. 411 00:25:29,000 --> 00:25:35,000 Let's say we actually go off, build two separate rigs, get them together, and see which one comes up with a better result. 412 00:25:35,000 --> 00:25:37,000 That sounds like a capital idea. 413 00:25:38,000 --> 00:25:39,000 Excellent. 414 00:25:39,000 --> 00:25:45,000 At long last, this centuries-old breakfast brain teaser is going to be put to the test. 415 00:25:45,000 --> 00:25:51,000 But why simply drop buttered toast when you can build an over-elaborate machine to do it? 416 00:25:51,000 --> 00:25:53,000 I love the Rue Goldberg approach. 417 00:25:53,000 --> 00:26:00,000 It's always funny to me to bring in pneumatics and other sciences to bear on something like toast falling off of the table. 418 00:26:01,000 --> 00:26:06,000 Adam goes over the top with a pneumatic device which mimics breakfast table mishaps. 419 00:26:07,000 --> 00:26:14,000 There are many ways toast can fall, but the most common it would seem to me is toast accidentally getting brushed off a table like that. 420 00:26:14,000 --> 00:26:19,000 Now, the question is, how to come up with a mechanical model that can repeat that type of action? 421 00:26:19,000 --> 00:26:22,000 And what I've got here is a top-loading toast tosser. 422 00:26:23,000 --> 00:26:27,000 Toast tosser is right. His solenoid valve is way too powerful. 423 00:26:30,000 --> 00:26:37,000 Now, there's a problem with my rig right off the bat, which is it's just throwing the toast like a Frisbee, like that. 424 00:26:37,000 --> 00:26:42,000 I was trying to think of something slightly more random that would brush it off the table like that. 425 00:26:43,000 --> 00:26:51,000 Adam recalibrates his rig, so instead of launching toast across the kitchen, it recreates the classic brush-off-the-table scenario. 426 00:26:52,000 --> 00:26:54,000 The toast tosser 2.0. 427 00:26:54,000 --> 00:26:58,000 First, he runs a control experiment with unbuttered toast. 428 00:27:05,000 --> 00:27:09,000 They're all starting topside up. Topside's labeled. 429 00:27:12,000 --> 00:27:15,000 Down. Down. 430 00:27:16,000 --> 00:27:22,000 He's hoping for a random sample where the toast lands topside up and down in equal numbers. 431 00:27:22,000 --> 00:27:29,000 We're showing totally consistently that a piece of toast just brush off, does one flip and lands topside down. 432 00:27:29,000 --> 00:27:30,000 With a certain pressure. 433 00:27:30,000 --> 00:27:36,000 With a certain pressure. So, I'll bet if we went to, you know, a thousand restaurants and shot a thousand people tipping toast off, 434 00:27:36,000 --> 00:27:39,000 it would probably be pretty close to this. That's what my intuition says. 435 00:27:39,000 --> 00:27:44,000 But it doesn't help. That is answering the question about people's proclivities to tipping toast. 436 00:27:44,000 --> 00:27:48,000 And the aim is to eliminate people from the toast dropping process. 437 00:27:48,000 --> 00:27:57,000 So Adam now wants a less naturalistic model, where the toast is suspended in mid-air and then dropped without any human intervention. 438 00:27:57,000 --> 00:28:04,000 In terms of the question, does toast, when it's buttered, prefer to fall to one side or the other? 439 00:28:04,000 --> 00:28:08,000 I think that's a question that's much better answered by Jamie's rig. 440 00:28:08,000 --> 00:28:12,000 Which, as you'll see, is a kind of a spring thing. 441 00:28:15,000 --> 00:28:16,000 There you go. 442 00:28:16,000 --> 00:28:19,000 But first, it's race day at Tahoe. 443 00:28:31,000 --> 00:28:35,000 I'm most definitely a morning person.
